BACKGROUND
The protection of crops from weeds and other vegetation which inhibit crop
growth is
a constantly recurring problem in agriculture. To help combat this problem,
researchers in
the field of synthetic chemistry have produced an extensive variety of
chemicals and
chemical formulations effective in the control of such unwanted growth.
Chemical
herbicides of many types have been disclosed in the literature and a large
number are in
commercial use. Occasionally, however, such herbicides can injure the crop
being protected
in addition to the weeds and other vegetation intended to be controlled.

As used herein, herbicide means an active ingredient that kills, controls, or
otherwise
adversely modifies the growth of plants.
As used herein, a herbicidally effective or vegetation controlling amount is
an amount
.. of active ingredient which causes an adversely modifying effect and
includes deviations from
natural development, killing, regulation, desiccation, retardation, and the
like.
As used herein, controlling undesirable vegetation means preventing, reducing,
killing, or otherwise adversely modifying the development of plants and
vegetation.
Described herein are methods of controlling undesirable vegetation through the
application of
certain herbicide combinations or compositions. Methods of application
include, but are not
limited to applications to the vegetation or locus thereof, as well as pre-
emergence, post-
emergence, foliar (broadcast, directed, banded, spot, mechanical, over-the-
top, or rescue), and
in-water applications (emerged and submerged vegetation, broadcast, spot,
mechanical,
water-injected, granular broadcast, granular spot, shaker bottle, or stream
spray) via hand,
backpack, machine, tractor, or aerial (airplane and helicopter) application
methods.
As used herein, plants and vegetation include, but are not limited to,
germinant seeds,
emerging seedlings, plants emerging from vegetative propagules, and
established vegetation.
As used herein, a safener is a compound that selectively protects crop plants,
in this
case corn (maize), from herbicide damage without significantly reducing
activity in target
weed species.
As used herein, agriculturally acceptable salts and esters refer to salts and
esters that
exhibit herbicidal activity, or that are or can be converted in plants, water,
or soil to the
referenced herbicide. Exemplary agriculturally acceptable esters are those
that are or can be
hydrolyzed, oxidized, metabolized, or otherwise converted, e.g., in plants,
water, or soil, to
the corresponding carboxylic acid which, depending upon the pH, may be in the
dissociated
or undissociated form. Exemplary salts include those derived from alkali or
alkaline earth
metals and those derived from ammonia and amines. Exemplary cations include
sodium,
potassium, magnesium, and aminium cations of the formula:

wherein RI, R2, R3 and R4 each, independently represents hydrogen or CI-Cu
alkyl, C3-C12
alkenyl or C3-C12 alkynyl, each of which is optionally substituted by one or
more hydroxy,
Ci-C4 alkoxy, Ci-C4 alkylthio or phenyl groups, provided that RI, R2, R3 and
R4 are sterically
compatible. Additionally, any two of R4, R2, R3 and R4 together may represent
an aliphatic
difunctional moiety containing one to twelve carbon atoms and up to two oxygen
or sulfur
atoms. Salts can be prepared by treatment with a metal hydroxide, such as
sodium hydroxide,
with an amine, such as ammonia, trimethylamine, diethanolamine, 2-
methylthiopropylamine,
bisallylamine, 2-butoxyethylamine, morpholine, cyclododecylamine, or
benzylamine or with
a tetraalkylammonium hydroxide, such as tetramethylammonium hydroxide or
choline
hydroxide.
Exemplary esters include those derived from CI-Cu alkyl, C3-C12 alkenyl, C3-
C12
alkynyl or C7-C10 aryl-substituted alkyl alcohols, such as methyl alcohol,
isopropyl alcohol,
1-butanol, 2-ethylhexanol, butoxyethanol, methoxypropanol, ally] alcohol,
propargyl alcohol,
cyclohexanol or unsubstituted or substituted benzyl alcohols. Benzyl alcohols
may be
substituted with from 1-3 substituents independently selected from halogen, Ci-
C4 alkyl or
alkoxy. Esters can be prepared by coupling of the acids with the alcohol using
any
number of suitable activating agents such as those used for peptide couplings
such as
dicyclohexylcarbodiimide (DCC) or carbonyl diimidazole (CDT); by reacting the
acids with
alkylating agents such as alkylhalides or alkylsulfonates in the presence of a
base such as
triethylamine or lithium carbonate; by reacting the corresponding acid
chloride of an acid
with an appropriate alcohol; by reacting the corresponding acid with an
appropriate alcohol in
the presence of an acid catalyst or by transesterification.

plant
growth may be damaged to a certain degree when an effective dose of herbicide
is used.
Safening as used herein means preventing the adverse effect of a herbicide on
the corn
(maize) plant, i.e., protecting the corn (maize) plant without, at the same
time, noticeably
influencing (i.e., overly diminishing) the herbicidal action on the
undesirable plant growth,
i.e., weeds, to be combated.

Examples:
.. Example I: Evaluation of Postemergence Herbicidal Safening in Corn (Maize)
Seeds of the desired test plant species were planted in Sun Gro MetroMix0 306
planting mixture, which typically has a pH of 6.0 to 6.8 and an organic matter
content of
about 30 percent, in plastic pots with a surface area of 103.2 square
centimeters (cm2). When
required to ensure good germination and healthy plants, a fungicide treatment
and/or other
chemical or physical treatment was applied. The plants were grown for 7-36
days in a
greenhouse with an approximate 14 hour photoperiod which was maintained at
about 18 C
36

during the day and 17 C during the night. Nutrients and water were added on a
regular basis
and supplemental lighting was provided with overhead metal halide 1000-Watt
lamps as
necessary. The plants were employed for testing when they reached the second
or third true
leaf stage.
Treatments consisted of ester (benzyl) compound of formula (1) (Compound A
benzyl
ester) and various safeners alone and in combination. Compound of formula (I)
and safener
components were applied on active ingredient basis.
For treatments comprised of formulated compounds, measured amounts of compound
of formula (I) were placed individually in 25 mL glass vials and diluted in a
volume of 1.25%
volume per volume (v/v) Agri-dex crop oil concentrate to obtain stock
solutions. If a test
compound did not dissolve readily, the mixture was warmed and/or sonicated.
Stock
solutions of the formulated safeners were prepared following the same
procedure.
Application solutions were prepared by mixing the required amount of each
stock solution
and addition of an appropriate volume of an aqueous mixture of 1.25% v/v of
Agri-dex crop
oil concentrate to the appropriate final concentrations of application
solutions.
For treatments comprised of formulated compound of formula (I) and technical
compound of safeners, weighed amounts of the technical materials were placed
individually
in 25 mL glass vials and dissolved in a volume of 97:3 v/v acetone/DMSO to
obtain stock
solutions at the highest safener concentration, and measured amounts of the
formulated
compound of formula (1) was placed individually in 25 mL glass vials and
diluted in a
volume of 1. 25% (v/v) Agri-dex crop oil concentrate to obtain stock solutions
at the highest
concentration. If a test compound did not dissolve readily, the mixture was
warmed and/or
sonicated. Application solutions were prepared by adding an appropriate amount
of each
stock solution and diluted to the appropriate final concentrations with the
addition of an
appropriate volume of an aqueous mixture of 1.25% (v/v) Agri-dex crop oil
concentrate.
Application solutions were applied to the plant material with an overhead
Mandel
track sprayer equipped with 8002E nozzles calibrated to deliver 187 liters per
hectare (L/ha)
over an application area of 0.503 square meters (m2) at a spray height of 18
inches (43 cm)
above average plant canopy. Control plants were sprayed in the same manner
with the solvent
blank.
The treated plants and control plants were placed in a greenhouse as described
above
and watered by sub-irrigation to prevent wash-off of the test compounds. After
20-22 days,
37
CA 02902743 2015-08-26
WO 2014/150740
PCT/US2014/024099
the condition of the test plants as compared with that of the control plants
was determined
visually and scored on a scale of 0 to 100 percent where 0 corresponds to no
injury and 100
corresponds to complete kill.
Colby's equation was used to determine the herbicidal effects expected from
the
mixtures (Colby, S. R. Calculation of the synergistic and antagonistic
response of herbicide
combinations. Weeds 1967, 15, 20-22.).
The following equation was used to calculate the expected activity of mixtures
containing two active ingredients, A and B:
Expected = A + B - (A x B/100)
A = observed efficacy of active ingredient A at the same concentration as used
in the mixture;
B = observed efficacy of active ingredient B at the same concentration as used
in the mixture.
Some of the compounds tested, application rates employed, plant species
tested, and
results are given in Table 1 through Table 13.

Example II: Evaluation of Safening of Isoxadifen-ethyl on the Phytotoxicity of
Compound A
Benzyl Ester on Maize (Corn)
Three field trials were conducted under commercial grower field conditions and
were
located in South Lebanon, OH, Weston, MO, and Newport, AR. Plot size was 3
meter (m) x
10 m (width x length) with 4 replicates per treatment. The corn crop was grown
using normal
cultural practices for fertilization and seeding, to ensure good growth of the
corn crop.
All treatments in the field trials were applied using a backpack compressed
air/gas
sprayer calibrated to apply 140 liters per hectare (L/ha) spray volume at
approximately 200-
400 kilopascals (kPa) nozzle pressure. Corn was either at the V2 (2-leaf) or
V5 (5-leaf) stage
of growth when the applications were made. Treatments were rated for visual
corn injury at
approximately 7, 14, and 28 days after application (DAA) as compared to the
untreated
control plants. Visual injury was scored on a scale of 0 to 100 percent where
0 corresponds
to no injury and 100 corresponds to complete kill. Treatments consisted of the
benzyl ester
of 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxypheny1)-5-fluoropyridine-2-
carboxylic
acid (Compound A benzyl ester), formulated as an SC (suspension concentrate)
applied at 15
grams active ingredient (g ai/ha) with or without isoxadifen-ethyl at 15 g
ai/ha. All treatment
results, both for the single product and mixtures, are an average of 4
replicates.
The expected activity of mixtures was calculated by Colby's equation as
described in
Example 1. Some of the compounds tested, application rates employed, plant
species tested,
and results are given in Table 14 and 15.
